RAILROAD-SWITCH.

SPECIFICATION forming part of Letters Patent No. 353,847, dated December 7, 1886.

Application filed November 27, 1885. Strial No. 184,119. (No model.)

To all whom it may concern:

Be it known that I, CHARLES M. CROSBY, of

Hillsborough, in the county of Highland and State of Ohio, have invented certain new and useful Improvements in Railroad-Switches; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to theaccompanying drawings, and to the letters of reference marked thereon,whieh form part of this specification, in which Figure 1 is a plan view of a portion of railroad-track having my improved switch applied; Fig. 2, a section on line 00 :0, Fig. 1. Figs. 3 and 4 are details of portions of the switch mechanism.

This invention relates to improvements in railway-switches, the object being to construct a switch in such manner that the necessity of frogs and guard-rails may be avoided and line of track made more clear; and it consists in the arrangement and novel construction of parts hereinafter described, and pointed out in the appended claim. 7

Referring to the accompanying'drawings by letter, A designates the switch lever pivoted on its standard a, and B represents the first section of the main track beyond the switchlever. O is the corresponding section of the side track or siding. The inner rails, b and c, of said sections have their ends outward from the switch-lever 'bolted toa solid transverse bed-rail, X, but have no frog adjacent to them,

as is usually the case.

D is the movable switchsection of track in front of the swith-lever, and connecting either with the section B or section 0 in the usual manner.

(2 is the switch-rod pivoted on the lower end of the lever A, and running thence to connect with the rails of the switch-section D. The said rod extends outward 011 the side of the track opposite the switch-lever, and has its other end pivoted to the lower surface of a disk, E, which lies and turns in a corresponding recess, e, in a block, 6, preferably of castiron. The block 6 is cylindrical, and is provided with a rectangular flange at its lower portion, through the angles of which the block is securely bolted in place.

The disk E has passing through it a short shaft. e the lower end of which passes through a central circular opening, 6 in the door of the recess 6, and has aproper head thereunder, as shown, so as to hold it in place. per end of the shaft 6 is threaded and receives the nut e, which presses down on the disk E and aids in keeping it in place.

6 is a cap or cover, which is screwed upon The upthe end of the shaft 6", outside of the nut e,and

which protects the disk from dust and dirt.

F is a rod having one end pivoted to the under surface of the disk E, running thence parallel with the section B of the main track, and

having its other end pivoted to the under surface of a disk,G, identical in construction with the disk E, and hereinafter described. The rod F passes through guide loops or brackets ff,which hold it down and in proper position The block and g is the cap or cover for the disk G. All

these parts are identical in construction with the corresponding parts of disk E and block 6.

h is a rod having its outer end pivoted to the under surface of block G, and running thence inward along the edge of the bed rail or tie X, 8

remote from the switclrlever.

h h are openings or slots in the cylindrical part of block G, and serving, respectively, for the passage of rods h and F.

I is a rail lying between the rails b and c of 0 the second section of the main and side tracks beyond the switch-lever. At the point i, where the said rails are a distance apart equal to double the width of the track with the width tie. Beyond that point, as far as the rail extends, it is similarly bolted down. All parts of the rail toward the switch from the point i are free to move laterally. Outward from the .ofa rail added, the rail I is bolted firmly to a 5 point i the rail I has a triangular block, v2,

' secured to it, which has an edge parallel with the rail 0 of the siding. The opposite side of the rail I is parallel with the rail B of the main track.

The inner end of the rod h is pivoted to the rail I, near the end which adjoins the ends of the rails b and 0, so that by turning theswitchlever inward-the disks E and G will, by means .of the described connecting-rods, turn on their axes, and by means of therod it cause the forward end of the rail I to correspond with the end of the rail b of the side track, so as to open said track and close the sideway. By reversing "the lever the siding is similarly opened and the main track closed.,

i i are chairs secured to the ties at and in front of the point i, and in which the movable portion of the rail I rests, allowing sufficient room in their recesses for the rail to have the proper movement, as described.

Some of the advantages of the described construction above those in ordinary use are that it is simpler, because in one line of rail in the second section the frogsand guard-plates are all dispensed with, and on account of their absence the switch is safer to travel over, as the lines of both main track andsiding are clearer. Having described my invention, I clain1 In a railway-switch, the combination of the switch-lever A, the sections of track, 13.0, and D, the disks E and G, the rods d, F, and h, the

blocks 6 and g, in which the disks are pivoted
